I would look for some of the 12" VHF pass cans. You want the true pass cavities
that have two connectors. Motorola, GE, DB Products and possibly others made
them. They show up surplus every so often and for a 600 KHz close spaced 2
Meter repeater they really shine.

Jim,
You're welcome! By definition, a "float voltage" cannot cook a battery,
since it is the voltage that the battery manufacturer specifies for
indefinite connection. This is what gel-cells used in alarm systems and
emergency lights are charged to, and they are floated continuously,
24/7/365.
And just to follow up on my suggestion, Comprod's site says that they offer
a line that will survive 200 MPH, heavy snow/ice.

Doug,
If your antenna is going to be subject to 100+ mph winds, it should be
braced at the top, and possibly in the middle as well. Moreover, there's no
way that any antenna that is supported only at the bottom will survive
extended exposure to high winds and ice buildup. The answer may be to

Thanks for that snippet. Thats the reference I was referring to when I
determined it was non frequency dependent. With the absence of further
responses from the group, I will consider my answer confirmed. Thank you all
for your time!

We closed my dad's photo studio in 1981, so it would

Certainly it will work as it is done all the time. Isolation is isolation -
if you have enough, it doesn't matter how you got it.

Ok just kicking this idea around the other day and the question came up about
antenna separation. I know the basic 2 meter antenna separation is 50ft. (I am
thinking 60ft to be safe) But is it possible to get them closer if I place some
cavities on either the receive or transmit sides. Sounds du
I would highly recommend the Kenwood TKR-850 there are many systems that use
these fine built repeaters. I would use the 25 watt power setting and buy a out

Hi Jim,
I have following this conversation thread over the past few days
and note your comments about overcharging. I have been through this
